Transcription

1 First Circular 10th International Workshop on Long-Term Changes and Trends in the Atmosphere (TREND-2018) May Hefei, China ( The 10th International Workshop on Long-Term Changes and Trends in the Atmosphere will be held in Hefei, China from 14 to 18 May The workshop themes are supported by the trends working group II.F of IAGA, ICMA, IAMAS, IUGG, VarSITI and SCOSTEP. The workshop is hosted by University of Science and Technology of China, and the venue will be Swan Lake Hotel in Hefei. Workshop website Workshop focus Long-term changes to Earth s atmosphere are becoming more and more relevant to the future of our world and it is paramount that we quantify and understand changes occurring at all levels within the coupled atmospheric system. The increasing concentration of greenhouse gases, stratospheric ozone depletion, varying solar and geomagnetic activity, secular change of Earth s magnetic field, and changing dynamics propagating up from the troposphere are some of the possible causes of long-term changes in the stratosphere, mesosphere, thermosphere and ionosphere. The goals of this workshop are to review the current state of knowledge about trends in these atmospheric regions, and we solicit papers to discuss what research is necessary for resolving inconsistencies, reducing uncertainties, and achieving a deeper understanding of middle and upper atmospheric climate change especially the relative influences of anthropogenic and solar effects. While the troposphere is not the main focus of the workshop, it is clear that it has a major role to play in middle and upper atmosphere trends; papers that demonstrate this relevance are also welcome. Topics on long-term variations of the atmosphere such as QBO, ENSO, MJO are all welcomed. Call for abstracts A formal call for abstracts will follow later. Abstract submission will open in late 2017.

2 Venue The workshop will be hosted at Swan Lake Hotel in Hefei, walking distance from University of Science and Technology in China. Hefei is the capital city of Anhui Province in central China, north of the Yangzi River that divides the province into two parts. The University of Science and Technology of China is a national research university in Hefei, Anhui, China, under the direct leadership of the Chinese Academy of Sciences. It is a member of the C9 League formed by nine top universities in China. The hotel is adjencent to the Swan Lake. 100 rooms at Swan Lake Hotel has been reserved. Single rooms with en-suite bathrooms will be available for ~$60 per night and single rooms with shared bathroom facilities will be available for ~$50 per night.
